Jim Bob and Michelle Duggar were preparing to welcome their 20 th child in April when a routine doctor's appointment revealed that Michelle had miscarried during the second trimester.

"I feel like my heart broke, telling my children," Michelle Duggar, 45, told People magazine today. "They have all been so excited about this baby and looking forward to April coming around and having a new little one in our arms. That was the most difficult. The Lord is the giver of life and he can choose when that life is ready to go on and be with Him."

Duggar and her family currently star in the TLC show, "19 Kids and Counting."

The family had planned to name the child and after finding out its sex.

Jim Bob Duggar told The Associated Press that his wife is "resting comfortably at home and asked for privacy."

This is not the first time the couple has experienced a challenging pregnancy.

Michelle Duggar miscarried what would have been the couple's second child, People reported.

In 2009, the couple welcomed their 19 th child, Josie, who was born 15 weeks early through c-section because Michelle Duggar suffered from preeclampsia.
